I will have the 800hp Griffin radiator, stock fans, and currently have an Meizere electric water pump. I think most of you guys would agree for HPDE and even Autox the EWP has to go. So if I go back to my stock water pump, will the upgraded radiator be enough to ensure adequate cooling? Is their a nicer pump that I should look into (something cost effective)?

I ran the electric water pump in my LS1 that had about 380rwhp without a single problem. When I changed to a 480rwhp LS3 I used an Edelbrock water pump which failed during an 8 hour race and replaced it with a parts store water pump that also failed during a race weekend. Both times I had to replace the water pump at the track. I'd try the electric pump and see what happens.
